The coherent control of the spontaneous emission spectrum of a driven atom in photonic crystals with two atomic position-dependent bands

Xianshan Huang, Hailian Liu

The coherent control of the spontaneous emission spectrum of a driven atom located within photonic crystals with two atomic position-dependent bands is investigated. The driving laser field splits the excited atomic level into a doublet that is further dressed by two bands bonded together with the atomic position in the crystal unit cell. The spontaneous emission spectrum of the atomic transition in free space is discussed. We find that frequency shift and the intensity of the spectrum can be perfectly manipulated by variation of the atomic position and detuning of the laser field. The result perhaps offers us an interesting route towards tunable photonic devices.

The control of spontaneous emission from a three-level atom in an anisotropic photonic crystal with two asymmetric bands

Xianshan Huang, Hailian Liu, Chengxiang Ding

We theoretically investigate the spontaneous emission light of an excited three-level atom embedded in an anisotropic photonic crystal with two asymmetric bands. The property of spontaneous emission relating to the atomic position in a unit cell of the crystal is described with a position-dependent phase difference. The atomic transition in free space can be manipulated by the other associated transition coupling to photonic crystal. The result shows that the spontaneous emission spectra are effectively shifted and tuned by the atomic position-dependent phase, which results in the asymmetric distribution of the photonic density of states between two bands, and the increasing band can push the emitted light towards the other band. The physical process can be further illuminated through analyzing the emitted field in photonic crystal. The result perhaps offers an interesting route towards tunable photonic devices.

Single-photon source in strong photon-atom interaction regime in quasiperiodic photonic crystals

Xingsheng Xu, Hongda Chen, Toshiki Yamada +1 more

The antibunching properties of the fluorescence from a two-level ideal system in a 12-fold quasiperiodic photonic crystal are investigated based on the calculated local density of states. We found that the antibunching phenomenon of the fluorescence from two-level ideal systems could be significantly changed by varying their positions, i.e. , perfect antibunching and antibunching with damped Rabi oscillation phenomenon occurred in different positions and at different frequencies in photonic crystals as a result of the large differences in the local density of states. This study revealed that the multi-level coherence of fluorescence from a two-level ideal system could be manipulated by controlling the position of the two-level ideal system in photonic crystals and the emission frequency in the photonic band structure.
